Specification of Letters Patent.

Patented April 23, 1907.

Application filed July 24, 1906. Serial No. 827,506.

To aZZ, whom it may concern.-

Be it known that I, HARRY E. SHARP, acitizen of the United States, residing at Rockville, in the county of Tolland and State of y and mold the corners thereof with one and the same shaping plate or die.

Primarily the object of the invention is the provision in a tool for accomplishing the Work described of means whereby said tool may be readily adjusted to set. the molding plate or die at any desired angle to the side plates of the device, either of said side plates being movable along and in line with the wall of the room on which the cornice is to be formed.

A further object of the invention is the pro vision of a pair of side bars hinged at their ends to form a triangular frame, a mold-carrier connected with the apex of said side bars and means cooperating with and guided by said mold-carrier for enabling a ready adjustment of the same to be made to change the angle of said side bars.

Afurther object of the invention is the pro vision of means for locking the adjusting de vices, as will hereinafter appear.

In the accompanying drawings, Figure 1 is a plan view of my improved cornice-molding tool. Fig. 2 is a rear end elevation of the same, showing the toggle-levers and the guide on the carrier for the forming tool or die. Fig. 3 is a side elevation. Fig. 4 1s a partial longitudinal section showing the manner of connecting the toggle-levers with the guide on the carrier for the forming plate or die, and Fig. 5 is a section on line 5 5 of Fig. 2.

Like numerals designate similar parts throughout the several views.

Referring to the drawings, the numeral 5 designates in a general way the triangular frame composed of side bars 6 and 7, pivoted together at their apex or otherwise connected to enable them to have a swinging movement, as at 8. Connected by hinges 9 1 fit within the groove.

in the form of the invention shown to the side bars 6 and 7 are toggle-levers 10 11, united at their upper ends by a joint 12. Plates 13 and 14 are secured to the side bars 6 and 7 overlapping each other, and each is provided with a slot 15, through which a thumb screw 16 passes and enters the base of a mold-carrier 17, said mold-carrier being mounted upon the overlapping side bars 6 and 7and its base having a erforation to receive the pivot 8 of said side ars, as shown in Fig. 5.

At the rear end of the mold-carrier is formed a guide-groove 18, which may be made in the body of said carrier or be in the form of a grooved metallic plate 19, secured to said mold-carrier. A bolt 20 passes through the overlapping ends of the togglelevers 10 and 11, and said bolt is equipped at its inner end. with a head 21, which enters the groove 18 in the end of the mold -carrier, and this head, while shown. as of elongated shape, may be of any other form desired to A thumb-nut 22 is threaded upon the bolt and serves to clamp the toggle members securely to the moldcarrier after the desired adjustment of the side bars has been made, and by loosening this thumb nut and screw 16 the plates 13 and 14 and toggle-levers 10 and 11 may be readily extended or withdrawn to change the angle of the side bars.

Designated by 23 is the mold or die proper, which in the form shown is inserted in a groove 24 of the mold-carrier, the sides of said mold-carrier being so shaped that the curves thereof coincide with the form of the molding-die. at the bottom of the mold-carrier, and the sides thereof extend up and embrace said carrier, beingsecured thereto by screws 25, as illustrated in Fig. 3.

From what has'been stated it will be evident that when it is desired to adjust the mold-carrier and to change the angle of the side bars 6 and 7 this may be readily accomplished by releasing the thumb-screw 16 and the thumb-nut 22, then moving the toggles up and down, the T-head of the bolt 20 serving as a guide for the movement of the togglelevers, and that after the desired adjustment has been made the plates 13 and 1 1, sliding upon each other, as above stated, said thumb screw and nut will be tightened to clamp the A channeled plate 25 is fitted parts rigidly in position. A wear or friction plate 26 may be employed on the bottom of the mold-carrier, if desired, said plate sliding upon the top plate 18, as will be evident.

From what has been stated it will be seen that the adjustment of the side bars to suit the angle required may be readily accomplished and that the device may be employed after the desired adjustment has been made to form a molding of any desired shape and turn the corners of said molding without the removal of said device from the position in in which it operates.

Interchangeable dies or forms of any kind may be substituted for those shown, the invention not being limited to the precise construction shown.

Preferably the parts will be made of metal, and in such case the guide-groove for the T- headed bolt, passing through the toggle-levers, will be made in the body of the moldcarrier. This is, however, unimportant, for the device may be made of any required material without departure from theinvention.

Changes may be made in the various details of construction, and other means may be employed for securing the toggledevcrs, if desired, the invention not being limited to the precise devices shown and described.

Having thus described the invention, what I claim is 1. The'combination, with devices mounted for swinging movement, of a mold or pattern carrier; and toggle mechanism connected with said carrier, and serving to adjust said devices.

2. The combination, with devices connected for swinging movement at their ends, and comprising a pair of elements pivoted to each other to constitute a frame, of a mold or pattern carrier; and toggle mechanism for adj usting said carrier.

3. The combination, with a pair of devices pivoted together, of a mold-carrier connected to said devices, and toggle-levers pivoted to said devices, and adjustable upon said carrier.

4. The combination, with a mold carrier and mold, of bars pivoted thereto, and toggle-levers connected to the bars, and united for sliding movement upon the mold-carrier.

5. The combination, with pivoted side bars, of toggles united for swinging movement to said side bars; a carrier having a groove at one end a formerp1ate secured to the other end of the carrier; and a securing device passing through the toggles, and having a head working in the groove of said carrier.

In testimony whereof I a'l'fiX my signature in presence of two witnesses.
